23 Qlaims.

, This invention relates to the art of typewritermanlfolding, and'particularly to improvements in the means for collating or assembling worksheets and interleaving or loading them with 5 carbon-sheets.

f It is usual for the operator to place a worksheet upon the desk, and deposit a carbon-sheet thereupon, and place a second work-sheet upon the carbon, and then deposit a carbon-sheet upon the second work-sheet, and then place a third work-sheet upon the latter, and so on, until the requisite number of work-sheets and carbons *is assembled; and then the pack is introduced into the typewritlng machine. After typing the page, the carbons are separated one by one from the work-sheets, and then used again for interleaving with work-sheets preparatory to typing the next page, and so on.

It is an object of the present invention to avoid the labor and loss of time involved in the usual method of preparation for manifolding,-as well as the usual slow picking of the sheetsapart after manifolding, and also to avoid waste of carbon which occurs in many instances, as for example where only a few lines are typed upon each page.

According to the present improvements, the typewriter-carriage may be provided with a sheet-loading bed, which may extend backwardly from the revoluble platen usually journaled upon the carriage; the bed having a gage for the leading edges of the work-sheets, and also preferably having opposite side gages adjustable for differthe work-sheets.

45 When this loading is completed, the platen is depressed to typing position, and presses the interleaved work-sheets down against the bottom feed-rolls provided upon the carriage, so that the sheets are gripped by the roll andplaten.

Said platen is mounted upon a swinging subframe; The mounting of the platen and-subframe may be similar to that which is commonly used for different purposes in Underwood typewriting machines.

v nae swinging of theplatenzupwardly and forsition.

wardly, according to the present invention, leaves room for the carbon fiy-leaves to be swung downwardly and forwardly singly upon'the deposited work-sheets.

' The loading box with its gages is so placed that 6 the forward ends of the work-sheets overlie the aforesaid feed-roll which normally runs upon the underside of the platen, for enabling said roll. to press the forward end of the pack of sheets up against the platen, when the latter is in lo printing position.

The platen is then rotated to bringthe worksheets forward and up to typing position. The typing of the page proceeds lineby 'line in the usual way. The fly-leaves or portions of the 15 carbon-plies which extend rearwardly from the pack of work-sheets to the spools, are drawn forwardly as said work-sheets feed around the platen; and they pull the spools forwardly.

The spools are preferably mounted upon a forgo wardly-swinging frame, which is hinged at its lower portion to-a support, and extends upwardly and rearwardly from its hinge to carry the spools.

After the typing of the page is completed, the platen is swung upwardly and forwardly in a 25 known manner. [The pack of work-sheets is thus brought to a fiat condition, and it is grasped by its forward edge andpulled forwardly out of the machine, leaving the flat carbon fly-leaves and spools undisturbed. The spools may be either 30. locked or frictionally held againstaccidental rotation. The spools may now be thrust rearwardly to normal position, together with the frame on which they swing; or a weak returning-spring may be employed for said spool-frame. 5

The, front sheet-gage rises automatically tonormal position preparatory to the next carbonloading operation, and it is dropped automatically when the platen is swung down to printing po- Thus the operation of manifolding page after page may proceed indefinitely. As soon as a leaf of carbon becomes worn, it maybe cut off and a fresh portionmay be pulled from the supply-' spool to serve as. a new 'fly-leaf. Means may be provided for cutting off the wom-outv section of carbon-web. Y

The front gage may be made finely adjustable forth and back to a moderate extent, so that when the work-sheets are advanced by the rotation of the. platen, the firstprintedblank line on the worksheet may be located accurately at the printing point, without the need of manual adjustment of the sheet.

Iftthe manifolding is done only near the botout removing it from the typewriter.

tom of the work-sheet, then only a corresponding short length of each carbon fly-leaf needs to be laid upon the sheet in the loading bed or ing it about its point of hinging to the carriage.

This will compact the device for shipment, with- The spoolframe may also fold forwardly; and the loading box is itself hinged so that it may tip downwardly and rearwardly and assume an upright position compactly at the back of the machine. The device may readily be applied to existing Underwood machines. Various devices may be adopted for adiustably stopping the rearward movement of the spool-frame, according to the work in hand.

Other features and advantages will hereinafter appear.

In the accompany drawings,

Figure 1 is a sectional side elevation of an Underwood typewriting machine fitted with the present improvements in their preferred form, and showing the parts in normal positions subsequent to loading the work-sheets with carbons.

Figure 3 is an elevation showing the compact collapsed condition of the spool-frame, the interleaving bed, etc.

Figure 4 is a sectional side elevation showing one work-sheet having been deposited upon the bed, and the carbon-leaves being held in the hand of the operator preparatory to being dropped singly upon the work-sheets; one dropped carbon being indicated by a dot-and-dash line.

Figure 5 shows all of the work-sheets and carbon-leaves assembled. or gathered.

Figure 6 shows the platen dropped upon the gathered sheets to grip the same against the feedroll, so that the pack may be advanced by the rotation of the platen.

Figure '1 shows the position of the parts when the typing of the page is completed; thespools having been dragged to their positions.

Figure 8 shows the platen as having been elevated to idle position, thus bringingthe worksheets and carbons to comparatively fiat condition. This view also shows the work-sheets gripped by their forward edges, to be pulled away from the carbons and out of the machine; whereupon the carbon-spool frame may be returned by its spring or handle 48 to its normal position at Figure l.

Type-bars i0 strike rearwardly against the front of a platen ll, upon a carriage 13 or the case-shifting platen-frame thereof. The carriage is provided with a letter-feeding mechanism, including a rack i4, said carriage traveling upon the usualrails l5, Ii, l1. Feed-rolls l8, l9 run upon the underside of .the platen, to co-operate with the latter in advancing the work-sheets. These feed-rolls may be cast off by means of a rocking cam-shaft 20 in the usual manner, if it should be desired to readjust the assembled workis a plan of the machine seen at Figextreme forward sheets while they are in position around the platen.

By means of an axle I2 the platen is journaled in a swing-frame, comprising arms 2|, 22 and a transverse connecting plate 23, the latter also functioning as a paper-shelf at the delivery side of the platen. This bail-swing-frame is hinged to move upwardly and forwardly upon studs 24 which project from opposite ends 25 of the papercarriage or of its case-shifting platen-frame. The platen H may be displaced upon this frame 2|, 22, 23 from the full-line printing position at Figure 1 to the dotted-line position, thus leaving ampleroom in the paper-carriage between the ends thereof for convenience in manipulating work-sheets in the manner herein explained.

Thebottom' of the empty work-space'in the carriage is occupied by the forward portion of a bed 26, upon which the work-sheets are deposited one by one. I'heir leading edges are set to a gage 21, while the latter stands in its dotted-line erect position, that is, while. the platen occupies its upwardly-displaced position at H. The platen is swung upon studs 24 from printing position to the dotted-line position at Figure 1 in a known manner, and remains elevated during the interleaving or loading of work-sheets and carbons.

Said paper-feed roll l9 may be located between the bed 26 and the sheet-gage 21, and the worksheets, when presented to said' gage, have their forward ends overlying said feed-roll. The lat-;

ter and the feed-roll l8 project up through openings in a curved paper-guiding apron 28, which underlies the platen forwardly of the bed 26.

The operation of assembling the work-sheets and carbons begins with the deposit of the first work-sheet upon the bed 26 and against the gage 21. The sheet usually overhangs the rear end of the bed, the latter extending towards a. set of carbon-web spools 29. A length of carbon is drawn off from one of the spools, to form a flyleaf, which is dropped upon the deposited worksheet 21, with the forward end of the carbon brought nearly to the gage 21 (Figure 4) Then another work-sheet is procured and dropped upon the carbon. A second carbon-leaf is brought forward, being obtained from the other spool 29; and it is dropped upon the upper work-sheet 21'. Then a third work-sheet is dropped, covering the second carbon, and so on, alternating worksheets with carbon-leaves, to the number desired (Figure 5).

This work of loading is expedited by opposite side gages 30 that are provided upon the bed.

The three gages and the bed form'a box to which the sheet fits, so that adjustment of the sheet is unnecessary. The gathered sheets overlie the main feed-roll l9.

The operator then swings the platen do wn from the displaced position il to the printing position II. The swing-frame 2|, 22, 23 is locked down by a latch 3i in a known manner. endsof the gathered sheets are gripped by the descending platen and the feed-roll i9, which may now co-operate to advance the pack of sheets and carbons around the platen to printing position (Figure 7).

'The front gage 21 is automatically withdrawn from the path of the advancing sheets by means of an arm 32, which is seen to project from a gage-frame 23. The arm 32 is depressed by an elbow 32 on the swing-frame, whereby said gageframe}! is turned down around its hinge 34 to The forward the Figure 1 position, with its gage lying idly below the paper-apron 28 (Figure 6).

If the work-sheets have been prepared with printed lines to receive the typing, then the working position of the gage 21 may be regulated accordingly'by means of a vertical stop-screw 35, which is threaded into a boss 36 on the carriage, to be adjusted up or down. The end of the screw stands in the path of an upright stop-rod 31, whose lower end is pivoted at 38 to an arm 39 of the hinged gage-frame 33. A spring 40 serves to raise the stop-rod 31 and the sheet-gage 21 as far as they will go, when the platen is elevated at II. By turning down the screw 35, the gage 21 may be finely adjusted in forward direction. This will allow the work-sheets to occupy a little higher position, so that the first line of typing may fall at the desired position on the sheet. During the typing, the platen and sheet are held by detent 39 and 'wheel 36.

During the typing of the page, the work-sheets,

together with carbons or fly-leaves 29 and spools 29, are drawn forwardly by the rotation of the platen (Figure 7) There is a considerable reach of carbon between the spools and the work-sheets at the completion of the typing of the page, for' the spools may not be advanced beyond the' dotted-line position seen at 29 Figure 1.

Each spool may be wound with a double or triple ply of carbon, according to the number of work-sheets that are to be manifolded, using one ply for each work-sheet. As many spools may be provided as may be desired, and the group may be carried upon the upper end of a swing-frame 4|, hinged at its lower forward end at 42 upon a support 43. v

During the typing of the page, it may be desired to rotate the platen backwardly at times, and in such a case the slack in the carbon-plies may be taken up by a light spring 44, coiled about the hinge-pintle 42. 1

After the typing of the page, a finger-piece 45 may withdraw the latch 3|, to release the swing- .frame, which then may be swung up to the dotted-line position at Figure 1. This inverts the work-table 23, which now occupies a horizontal forward position at 23 and the typed work-sheets may be grasped by their ends and pulled forwardly, to strip them from the carbonleaves and withdraw them from the machine. The carbon-leaves and spools may be returned by the spring 44, or by a suitable handle 46 connected to the spool-frame.

The carbon-spool frame is arrested by a stopdevice including a slotted link 41 that connects a stud 48 of the spool-frame with a stud 49 on the fixed support 43. The link is provided with a series of slots 50, affording adjustment of the spool-frame stop, according to the kind. of work in hand. The stud 49 is provided with a flat swiveled block 5| fitting in a longitudinal slot 52 in the link and adapted to passover the notches 56 during the forward stroke of the spool-frame. The parts are now in position -to assemble the work-sheets with interleaved carbons, prepara-' tory to typing the next page;

During the pulling of the carbons forwardly at the typing operation, and during the movement of the spools rearwardly at the carbon-stripping operation, the spools "maybe held against rotation by any suitable locking device, or by friction washers 5 3.

. The bed 26 occupies a depressed position in the machine, as compared with the delivery table 23,

and is inclined downwardly and forwardly so -passing the sheets and carbons into the bite of the platen and feed-roll is expedited. When any carbon fly-leaf becomes worn, it may be sheared oif or the machine may be provided with a car hon-shearing knife 53*- of known construction, adjacent to the platen.

When only a short lower portion of each sheet is to be overlaid with the carbon-leaf, a portion of the leaf may drop between the table 26 and the carbon-spool, to form a, carbon-loop, and the weight of the overlying sheets will afford'suffl cient friction to hold the carbon-ends so that they may take up the slack in the loop as they are advanced by the work-sheets. Loops may also be formed, if desired, by swinging the spoolframe forward and looking it there, even after the forward ends of the carbon fly-leaves have been set nearly up to the gage 21. For this purpose, the spool-frame 4| may be swung forwardly and the stud 48 placed in a different notch 50,

so that the lengthy carbon-loop will fall between the rear of the work-sheets and the spools.

Adjustment of the sheet-gathering box may be provided by forming the bed 26 in two sections, 26'and 26 at Figure 2. These sections may approach or recede from each other, being held by means of screws 54 to a transverse supporting bar 55; the screws passing through adjustmentslots 56 parallel with'the platen. I

To prepare for shipment, the support 43' may be swung forward about its hinge 51 to occupy a pendent position at the back of the typewriting machine 58. Said hinge 51 is provided in a bracket 59, which is secured by bolts 60 to the main bar |3 of the carriage. The support 43' may be held by a wing-screw 6|, Figure l, in either collapsed or extended condition. When said support is collapsed, the spool-frame 4| may be collapsed forwardly about pivot 42, and stand compactly behind the typewriting machine. The loading box 26 may be tipped to a compact vertical position behind the typewriter; the box being for this purpose provided with legs 62, which are hinged at 63 to the upper portion of the bracket The brackets 59 are supported from the same fixture 64 that carries the usual tabulator-rack 65,-Figure 1.

In unfolding the frames to working positions, the table 26 is swung up about the hinge 63, to the position at Figure 1. Then the support 43 is swung up, and a pin 66 thereon is brought to a position beneath a pin 61 that projects from the leg 62 of the table. 'Then the table is permitted to drop a trifle. until its pin 6'! rests upon said pin 66, which affords a permanent support for the table.

The interleaving table or box 26 overlies the tie-bar 68 of the frame 25, which is the caseshift frame of the paper-carriage. Said tie-bar is depressed for that purpose, below its formerplaten-gear l0 and a companion gear II that is controlled by a knob 12; thisbeing a known construction. By this means operative connection is preserved between the platen and the knobs, and also between the platen and the line-space wheel 39 while the platen is in elevated position.

Each carbon-spool may bedetachable. For example, its square shaft 13 may be reduced at 74, permitting the shaft to be pressed to the left (against compressive tension of spring 15) far enough to clear the right-hand end of the shaft from the side 15 of the spool-frame, permitting the spool to be withdrawn.

Each carbon-spool being keyed to its shaft, there is provided the light spring 15, which may be so weak as to yield readily to a sudden pull upon the frail carbon-web, thus minimizing the liability of the latter to become damaged from tearing. The spring will suffice to return the spool to normal rotative position when the web is released from tension.

A length of web may be permanently pulled oil from either spool, which for this purpose may be provided with a friction washer 53, bearing against the inner face of the fixed plate 16, being held in frictional contact by the same spring 15. The washer is rotated by means of an arm 11 on the spool-shaft. The arm strikes a pin 18 projecting from the washer. In operation, the spring will yield to ease the pull of the web, while the washer remains stationary; but after the spool has been given an idle revolution by means of the pull, the arm H strikes the pin '18, and

further, gradually increased pull on the web causes it to be paid off permanently from the spool. At this time the washer and spool rotate together. When sufficient of the web has been paid off, it is released, and the spring 15 will react to the extent of say one revolution. The adjacent portion of the web rewinds upon the spool, and the spring resumes its normal function of lightly restraining the web against pull. It will be understood that the spring will yield to a light pull; but the frame itself will yield to the pull of the web and rock upon its hinge 42 after the spring is tautened. The handle 46 may be grasped to hold the spool-frame steady during the pulling ofa fresh length of web off from either spool; said handle being 'pivoted at 19 to the spool-frame. The arms 4| are connected by a tie-bar at their upper ends, completing the ribbon-spool frame.

A work-sheet and carbon-web intercalating typewriter, having in combination a platen, an intercalating table, means to co-operate with the platen for seizing the intercalated worksheets and carbons, and to carry them around the platen, a carbon-spool, a spring yielding to permit slight slack rotation of the spool, to avoid injury to the carbon by a sudden pull on the latter, means to limit such slack rotation of the spool, and including means for enabling the spool to be further unwound at will, said spring operating to return the spool to rewind the slack carbon thereon, ready to slacken again at the succeeding jerk of the carbon, a frame whereon said spool is mounted, said frame yieldable to the pull of the carbon as work-sheets and the interleaved carbon are line-spaced with the platen, and a light returning spring for said frame.

' "-20. A work-sheet and carbon-web intercalating typewriter, having in combination a platen, an intercalating table, means to co-operate with the platen for seizing the intercalated worksheets and carbons, and to carry them around the platen, a carbon-spool, a spring yielding to permit slight slack rotation of the spool, to avoid injury to the'carbon by a jerk on the latter.

means to limit such slack rotation of the spool and for enabling the spool to be further unwound at will, said spring operating to return the spool to rewind the slack carbon thereon, ready to slacken against the succeeding jerk of the carbon, a frame whereon said spool is mounted, said frame yieldable to the Jerk of the carbon as work-sheets and the interleaved carbon are line-spaced with the platen, a light returning spring for said frame, and means adjustable for determining the" normal podtio'n of said frame.- v

21. .A work-sheet and carbon-web inter-catating typewriter, having in combination a platen, an intercalating table, means to co-operate with the platen for seizing the intercalated worksheets and carbons, and to carry them around the platen, .a' carbon-spool. means rotatably mounting the carbon-spool, said mounting means being supported fpr movement toward and from the platen, aflspring arranged to yield and permit idle rotation of the spool, instead of bodily advance of fthe spool with the mounting means, thereby to provide slack and hence avoid injury to the carbon by ajerk onthe latter, and means to limit such idle rotation of the spool, said spring operating to return the spool to rewind the slack carbon thereon, ready to slacken again at the succeeding jerk of the carbon.

22. A work-sheet and carbon-web intercalating typewriter, having in combination a platen, an intercalating table, means to co-operate with the platen for seizing the intercalated work-sheets and carbons, and to carry them around the platen, a carbon-leaf holder, a support for said holder mounted so as to be movable in opposite directions, in accordance with the line-space feed and retraction of the carbonleaf relative to said platen, and means to prevent injury to the carbon-leaves, including means resiliently connecting said carbon-leaf holder to said support, whereby a jerk upon the carbon-leaf, instead of subjecting the carbonleai to a'tearing strain, due to the inertia of the support, results in said holder having a limited prior movement relative to said sppport to avoid said strain, said resilient connecting means operating to restore the holder ready to yield at a succeeding jerk oi the carbon-paper. 23. In a typewriting'machine, the combination with a carriage, of a revoluble platen, a sheetgathering bed in the rear of the platen, a carbon-supply movable with the carriage and from which fly-leaves are successively movable to a position face up, and. their free ends foremost, on said bed in alternation with separate worksheets, a gage for the bottom ends of the worksheets, said gage being movable to idle position out of the path of the gathered sheets,

means operable to .cause said gathered sheets to assume a feeding position upon the platen,

and means co-operative with the revoluble platen-
